MLFB_HomeUsingCurrentPosition

Pipe Network motion icon

Function Block A function block groups an algorithm and a set of private data. It has inputs and outputs. - Homing The Homing procedure allows, based on a position measurement, to set a position offset to the motor in order to ensure it is physically at the home position using current position.

Inputs

Input	Data Type	Description
ibExecute	BOOL	Start homing, edge-triggered.
iAxisID	DINT	ID of the axis block of the Pipe Network.
iPosition	LREAL	Reference position.

Description

obDone

BOOL

Done bit.

obActive

BOOL

Active bit.

obError

BOOL

Error bit.

oErrorID

DINT

Error identifier:

ErrorID	Description
1	Axis in error.
2	Axis is not enabled.
3	Timeout exceeded or expired.
4	SDO read/write error.
5	Input parameter out of range.

Remarks

Use this parameter to set the value of the home position other then zero.
- This allows you to offset your home reference away from zero.
Using the current position is the most basic homing method.
- This method uses the current position of the motor as the home point reference.
